The first frost hits, and most gardeners reluctantly hang up their gloves, pack away their tools, and wave goodbye to fresh greens until spring. But the ones who know better—the clever few—quietly stroll out to their yards with a smirk because they’ve got a secret weapon: the cold frame. A simple box with a clear lid might not look like much, but it’s basically a magic trick for plants, stretching the growing season long after everyone else’s garden has gone to sleep.
Sure, it’s great for lettuce, but that’s just the appetizer. The truth is, cold frames can extend far more than salad greens—they can transform the way you garden all year long.
